Nielsen has released its Twitter TV ratings, showing that there has been a 38 percent increase in tweets about TV in the US over the last year — from 190 million in Q2 2012 to 263 million in Q2 2013. The number of Twitter TV authors in the US has also risen 24 percent, from 15 million to 19 million in the same period.

At first glance, the data also shows that the Twitter audience for an average TV episode is 50 times larger than the number of authors who are tweeting.

This means that if 2,000 people are tweeting about a TV show, 100,000 people are seeing those tweets, Social Guide — part of NM Incite, a joint venture between Nielsen and McKinsey — explains.

Social Guide is also rolling out a Nielsen Twitter TV Ratings Weekly Top Ten list. The latest list as of October 6 shows that the TV show most talked-about on Twitter was Scandal. The previous week measuring tweets from September 23 – 29 showed that Breaking Bad occupied the top position.

As Twitter inches closer to its IPO, TV will be a huge part of what it does to appeal to advertisers and in turn, investors. In August, a new study from Nielsen concluded that tweets can cause a “significant increase” in viewership of broadcast TV programs 29 percent of the time.
